Penny

Pennies are things we use to buy things. They have the face of Abraham Lincoln on the front. They have his monument on the back. Pennies are really hard. They have dates of when it was made.

I actually think a penny is made of some kind of metal. It doesn't have any gas or nothing in it. I think it has some kind of metallic element. People still don't know what's in pennies. I'm going to do some research on it.

Made of; Zinc and Copper
